摘　　要：为了满足大型以太网LED灯饰控制系统的实时仿真需求,方便工程施工人员快捷高效地安装LED灯具,在基于Visual C++和Open GL对LED灯具进行建模仿真的传统方案基础上,利用拣选射线拾取法实现对LED灯具的流畅编辑操作;同时使用Win32平台下的底层网络监听开发包Winpcap实现对以太网数据链路层数据的捕捉,并根据其帧格式和系统自身的数据格式实现对像素信息的分析和提取。最后在双缓冲和显示列表技术的支持下,通过实验验证了所设计的LED灯饰系统的实时动画仿真显示效果。For meeting the demand of real-time simulation of large-scale Ethernet LED lighting control system and facilitating the project construction personnel to install LED lamps quickly and efficiently, based on traditional scheme, which uses Visual C ＋ ＋ and OpenGL to model and simulate LED lamps, the choosing ray pick-up approach is used to realise smooth editing operation on LED lamps; at the same time, the underlying network monitoring development packet Winpcap on Win32 platform is used to implement the capture of data in Ethernet data link layer; moreover, the analyses and extraction of pixels information is implemented according to Ethernet MAC frame format and the data format of the system itself. At last, with the support of double buffering and display list technology of OpenGL, the display effect of real- time animation simulation of LED lighting system is verified by experiment.
